Product details
Overview
R5F51405BGNE#30 from Renesas is a 48 MHz, 32-bit RXv2 core MCU with on-chip FPU, 128 KB flash, 32 KB SRAM, and hardware AES/RNG encryption. It integrates CAN, 6-channel MTU2, 12-bit A/D (11 external channels), D/A (2×8-bit), CTSU2SL capacitive touch (24-key self-capacitance), RTC, and IEC60730 safety support - deployed in industrial HMI and sensor gateway control.
For engineers reviewing the R5F51405BGNE#30 datasheet, R5F51405BGNE#30 pinout, R5F51405BGNE#30 application, or R5F51405BGNE#30 equivalent, this page delivers verified package mapping (PWQN0048KC-A, 48-pin HWQFN, 7×7 mm, 0.5 mm pitch), confirmed low-power modes (0.25 µA standby), real-time clock operation, CAN 1 Mbps compliance, and encryption module availability - all validated against Renesas R01DS0379EJ0120 Rev.1.20.
Technical Context
The R5F51405BGNE#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754-compliant 32-bit FPU - enabling deterministic floating-point math at 48 MHz. Its memory subsystem includes no-wait SRAM, 128 KB flash with 1.8 V programming, and 8 KB data flash supporting background operation (BGO) for firmware updates without halting execution.
Peripherals are orchestrated via Event Link Controller (ELC), allowing timer-triggered ADC conversions and CAN message transmission without CPU intervention. The device supports dual-voltage detection (LVD0–LVD2), independent watchdog (IWDT) with dedicated 15 kHz oscillator, and low-power timer (LPT) active during software standby - critical for battery-powered edge nodes requiring sub-µA sleep current and 6.2 µs wake-up latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F51405ADNE#30 | No AES/RNG hardware; same 128 KB flash, 32 KB SRAM, and PWQN0048KC-A package. | Lacks cryptographic acceleration - unsuitable for secure firmware updates or TLS offload. | Select when IEC60730 functional safety suffices without data-at-rest encryption requirements. |
| R5F51403AGNE#30 | 64 KB flash, 16 KB SRAM, 4 KB data flash; retains AES/RNG, CAN, CTSU2SL (24-key), and same -40 to +105°C rating. | Reduced memory footprint limits complex UI or large OTA update buffers. | Choose for cost-sensitive, compact designs where 64 KB flash meets firmware size constraints and full peripheral set is retained. |
Compared with R5F51405BGNE#30, R5F51405ADNE#30 removes encryption but matches all timing, analog, and communication specs - ideal for non-secure legacy upgrades; R5F51403AGNE#30 trades memory capacity for identical security and interface capability - better suited for space-constrained thermal or sensor nodes.
